Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically an electric universal tooling for assembling excavator tracks. Background Technology

[0002] Excavator tracks are a crucial part of the excavator's traveling mechanism. Wrapped around the track beam, they provide a large support area or a low ground pressure, preventing the excavator from sliding or excessively slipping when descending slopes, thus improving the excavator's stability and safety. However, tracks frequently bear axial and alternating forces during operation. Improper assembly not only wastes significant manpower but also leads to premature wear and other quality issues, such as damage to the drive wheels and track rollers.

[0003] Traditional excavator track assembly involves using a crane to lift the track pin mounting holes, then moving the crane up to its upper limit and back and forth to wind the tracks. This method is inefficient, causes wear and tear on the lifting tools, and poses numerous safety hazards. Designing an efficient and safe excavator track assembly fixture has become an important part of the technical design for excavator manufacturers.

[0004] Announcement No.: CN111112982B discloses an automated assembly equipment and method for excavator tracks. The assembly equipment includes a shuttle car with a lifting structure that travels on the assembly station line and carries the lower frame assembly; a conveyor that transports the tracks to both sides of the assembly station line; a roll-up machine located on both sides of the assembly station line for lifting the tracks into a flattened or rolled state; a spreading platform for carrying the flattened tracks; a track chain presser for pressing the rolled tracks; and a pusher for pushing the flattened tracks to the rolling position.

[0005] The existing technology uses a rolling machine to wrap the track to be assembled onto the underframe assembly, which is less efficient than the present invention.

[0006] Announcement No. CN219257557U discloses a track mounting device and system, including: a fixed frame, a first tensioning mechanism for tensioning the track, a second tensioning mechanism for tensioning the track, and a drive mechanism for driving the first tensioning mechanism and the second tensioning mechanism to slide. The first tensioning mechanism is slidably mounted on one side of the fixed frame, the second tensioning mechanism is slidably mounted on the other side of the fixed frame, and the drive mechanism is mounted in the middle of the fixed frame. Both the first tensioning mechanism and the second tensioning mechanism are connected to the drive mechanism.

[0007] The existing technology uses a drive mechanism to drive the first tensioning mechanism and the second tensioning mechanism to slide relative to each other, thereby spreading the track and achieving the effect of track installation. However, this existing technology cannot be adapted to different models of track frames.

[0008] Announcement No. CN217143025U discloses a track assembly line and a tracked machinery production line. The track assembly line has an unfolding loading position, a pushing initial position, and a track assembly position, and includes: an unfolding mechanism configured to unfold a coiled track located at the unfolding loading position and lay it at the pushing initial position; a pushing mechanism configured to push the track laid at the pushing initial position to the track assembly position along a direction perpendicular to the unfolding direction of the track; and an assembly mechanism configured to surround the track located at the track assembly position onto a vehicle body placed on the track.

[0009] The assembly efficiency of the existing track technology is not as good as that of this invention.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.
